Question

Use matlab. I need help.

2. beisider the two matrices: AIN: In(2) ?/21 1+2/j V3j ')-=h? -1 10 Use MATLAB to compute items 4 below: a)A+3B c) A3B2-A-B e) B'A b) AB +I I is the Identity matrix; MATLAB: "eye (n) " command. d) A' (Same as A" i.e. complex conjugate transpose. For transpose use A) f BTA (This is regular transpose, not complex conjugate.) Attention: Don't use . or *as the dot disables matrix operations rules and changes them into element by element operations. Attention: Don't use eye alone as it is not the identity matrix, must use eye (2) which is the 2 x 2 identity matrix

Explanation / Answer

MATLAB Commands

A = [log(2) pi/2 ; 1+2i sqrt(3)*i]
B = [ -1 10 ; pi/4 4+i]

display('a')
A + 3*B

display('b')
A*B + eye(2)

display('c')
A*A + 3*B*B - inv(A)*B

display('d')
A'

display('e')
B' * A'

display('f')
transpose(B) * transpose(A)

Output
